Hi

I applied a new coat of acrylic paint on concrete a couple of days ago.


I etched the concrete with commercial etching solution and ensured it
was clean before applying the paint.

But was it bone dry?


It is now bubbling in the heat of the day.

Is there any way to fix the bubbles? Should I puncture them?

Did you use a paint specifically formulated for concrete? Paint
products vary widely in their properties,. For example, acrylics are
superior for outdoor use, polyurethanes are best for wear resistance
and epoxies are noted for good adhesion to concrete. Consider visiting
a real paint store, like Sherwin-Williams, for advice and council, in
addition to a phone call to customer service of the company that made
your paint. Understanding the product is the key to success. Good luck.
